Iron aluminides do not generally show good aqueous corrosion resistance. The present study attempts to improve their corrosion resistance by prior surface oxidation. While good corrosion resistance can indeed be obtained, it is found to be difficult

High temperature structural coarsening of an ODS FeAl intermetallic
Autor: Mª Antonia Muñoz-Morris, David G. Morris, C. García Oca
Publikováno v: Intermetallics. 11:425-434
The coarsening of oxide particles and grains in an ODS FeAl intermetallic has been examined during annealing at high temperatures under conditions where recrystallization does not yet occur. Coarsening of the yttria particles is shown to be controlle

instname
The mechanical behaviour of equal channel angular pressing (ECAP) processed Al-3Mg was examined by compression testing in a direction normal to the processing directions. ECAP-processed materials showed no initial yield plateau and needed significant

Influence of machining conditions on tensile stress and ductility of a mechanically alloyed Fe–40Al intermetallic

Publikováno v: Digital.CSIC. Repositorio Institucional del CSIC
instname
The influence of a variety of machining conditions on the tensile behaviour of a mechanically alloyed FeAl intermetallic has been examined. Yield behaviour is hardly affected by machining conditions, and ductility is only weakly sensitive to machinin

Microstructural evolution of dilute Al–Mg alloys during processing by equal channel angular pressing and during subsequent annealing
Autor: Mª Antonia Muñoz-Morris, David G. Morris, C. García Oca, Gaspar González-Doncel
Publikováno v: Digital.CSIC. Repositorio Institucional del CSIC
instname
Equalchannelangularpressing (ECAP) is a materials processing method that allows very high strains to be imposed, leading to extreme work hardening and microstructural refinement, with minimal change of external sample dimensions. It offers possibilit

instname
Deformation and fracture mechanisms leading to tensile failure have been examined in a mechanically-alloyed and a recrystallized Fe-40A1 intermetallic. It is shown that tensile failure begins by the initiation of a small crack near the sample surface

An iron aluminide alloy of base composition Fe-40Al has been prepared by mechanical alloying and processed using a variety of powder consolidation methods and heat treatments to produce a range of grain sizes and oxide dispersoid sizes. The strengths
